Read Acts 17 today.

Paul was involved in a discussion with the philosophers and the council in Athens. They were people who had what I call a generic belief in God. Their belief was not in specific god, but rather in a nebulous idea of god. This view is not uncommon today. How many people would be willing to say, “Sure, I believe in god”, yet they be unable to find words to explain what that means?
What Paul was trying to do with the people of Athens was to help them explore farther, to help them move from a generic, undefined belief to one that is more specific.
Do you know anyone like that? Would you be willing to have a discussion about what they believe about God? Listen to what they believe. Ask questions. Perhaps there will also be an opportunity to share what you believe.
Acts 17:18-23 NLT
He also had a debate with some of the Epicurean and Stoic philosophers. When he told them about Jesus and his resurrection, they said, “What’s this babbler trying to say with these strange ideas he’s picked up?” Others said, “He seems to be preaching about some foreign gods.” [19] Then they took him to the high council of the city. “Come and tell us about this new teaching,” they said. [20] “You are saying some rather strange things, and we want to know what it’s all about.” [21] (It should be explained that all the Athenians as well as the foreigners in Athens seemed to spend all their time discussing the latest ideas.) [22] So Paul, standing before the council, addressed them as follows: “Men of Athens, I notice that you are very religious in every way, [23] for as I was walking along I saw your many shrines. And one of your altars had this inscription on it: ‘To an Unknown God.’ This God, whom you worship without knowing, is the one I’m telling you about.
